< cpp‎ | ranges‎ | adjacent transform view‎ | iterator

constexpr decltype(auto) operator*() const noexcept(/* see below */); |  | (since C++23)

Returns the current element in the `adjacent_transform_view`.

Let `parent_` and `inner_` be the data members of the iterator. Equivalent to:

    return apply([&](const auto&... iters) -> decltype(auto)
                 {
                     return invoke(*parent_->fun_, *iters...);
                 },
                 inner_.current_);

### Parameters

(none)

### Return value

The current element.

### Exceptions

Let `Is` be the pack `0, 1, ..., (N - 1)`.

`noexcept` specification:
noexcept(std::invoke(*parent_->fun_, *std::get<Is>(inner_.current_)...))
